Multiple Update Query in Access

[Mac1206]

Hello, I'm trying to find a way to combine multiple update queries that are updating one table into a single query and I'm unsure of how to create it...Is there a way to do this and if so can you provide an example please...Thanks for your support...

It really depends on what the queries look like, to see if they can be combined into one query with reasonable effort. Can you post the SQL code of each query?

Note that there is nothing inhererntly wrong with having more than one update query. If the issue is the effort it takes to run them all, you could put them all in a macro, and then simply run that macro with a single click.

That is what we are trying to get away from, so many marco's...

1. UPDATE BSMTimeTableTemp SET BSMTimeTableTemp.ReferenceNumber = [PaymentID], BSMTimeTableTemp.PaymentID = [ReferenceNumber];


2. UPDATE BSMTimeTableTemp SET BSMTimeTableTemp.[1099Code] = "0"
WHERE (((BSMTimeTableTemp.DisbursementType) Like "*Loan*"));


3. UPDATE BSMTimeTableTemp SET BSMTimeTableTemp.InstitutionName = [Institution_FurtherName]
WHERE (((BSMTimeTableTemp.DisbursementMethod) Like "*ACH*" Or (BSMTimeTableTemp.DisbursementMethod) Like "*Wire*"));


4. UPDATE BSMTimeTableTemp SET BSMTimeTableTemp.DistributionType = "*" & [DistributionType]
WHERE (((Right([DisbursementType],1))="*"));

You couldn't run those as one query.

Why not create a function that runs the update queries?

You would only need to pass it the database connection and the appropriate SQL string.

Why not combine them into one Macro?
You can perform multiple steps in a Macro.
Or convert it to VBA code and run all those commands with one procedure (or function, like Norie recommended).

I agree with the others here that it would be better to run the 4 queries in sequence, however, I think you probably could combine them in one query albeit a somewhat inefficient query:

UPDATE BSMTimeTableTemp SET PaymentID = [ReferenceNumber], [1099Code] = IIf([DisbursementType]  Like "*Loan*","0",[1099Code]), InstitutionName = IIf([DisbursementMethod] Like "*ACH*" Or [DisbursementMethod] Like "*Wire*",[Institution_FurtherName],[InstitutionName]), DistributionType = IIf(Right([DisbursementType],1)="*","*" & [DistributionType],[DistributionType]);

I'm new ti this so how would I do this, do you have any samples for me to follow....

Not really sure about the easiest way with a macro - I think just use the open query command 4 times and point to your query (might want to set warnings off & back on to stop the prompts).

code wise:

With CurrentDb
.Execute "UPDATE BSMTimeTableTemp SET BSMTimeTableTemp.PaymentID = [ReferenceNumber]", dbFailOnError
.Execute "UPDATE BSMTimeTableTemp SET [1099Code] = '0' WHERE DisbursementType Like ' * Loan * ' ", dbFailOnError
.Execute "UPDATE BSMTimeTableTemp SET InstitutionName = [Institution_FurtherName] WHERE DisbursementMethod Like '*ACH*' Or DisbursementMethod Like '*Wire*'", dbFailOnError
.Execute "UPDATE BSMTimeTableTemp SET DistributionType = ' * ' & [DistributionType] WHERE Right([DisbursementType],1)='*'", dbFailOnError
End With


MsgBox "Complete"

Either add this to a new sub routine within a module or assign it to a button on a form (this would be normal practice). Create a new command button, go to properties for it and on the event tab select the 3 dots beside on click. Select code builder and then paste the code above between the sub & end sub lines.

Exactly. It is as simple as starting a new Macro, and using the OpenQuery command four times, once opening each query. Then to run all of them in sequence, all you need to do is to run that Macro.

And you can easily convert that Macro to VBA code, if you want, by selecting it and then clicking on the "Convert Macros to Visual Basic" button in the Macro menu. That is helpful if you want to convert that macro to a procedure or function, or want to make it more dynamic.
